Okay, #xesam and let's discuss.

Okay. This is great news btw.

I'll just put this straight, because I want these things to be very
We will ignore every anti troll. From which wind direction the troll
came doesn't matter.
We're not interested in politics, we're interested in innovation.
The streamanalyzer library is innovation. That's why we are interested
This doesn't mean that we don't want a clean dependency tree.
Technically it doesn't make sense for Tracker to depend on the entire
strigi stack, we just want streams and streamanalyzer.

That's a very good idea, yeah.

We'd like to start a freedesktop project to host a shared package
containing the ontologies in the TriG format.
We hope that you guys at strigi and people like Sebastian Trüg join us
on that. I will try to visit the conference in Amsterdam as I understood
Sebastian will be at that conference too?
I tried to get us to actually make this package at the desktopsummit in
Gran Canaria but apparently I failed. We did succeed in agreeing on most
of things that had to be agreed:
- TriG format
- A load order index file, also in TriG or Turtle instead of filenames
with numbers upfront the filename
- Custom ontology install procedure should be well defined
- Shared location using XDG dir specifications
- I think we even decided that we'd use autotools for the build
- etc (I hope somebody of the group who was discussing this at the
balcony has kept a list in his mind)
We should start this project as soon as possible to avoid that softwares
like indeed, streamanalyzer, need to drag ontologies along.
Right now we need to do this for Tracker too. We'd *very* much like to
have this as a shared package between all the Nepomuk projects.
So let's start this? What are we waiting for? #xesam and let's code!
